Public-record transcripts, run through the free Deposition Grader. No human picks the flags — the same input produces the same output for anyone. The witnesses are famous. The patterns are the ones in your cases.
Free and private — everything runs in your browser, so nothing is uploaded. The Grader is the 10% version: Demur does this live, while the witness can still answer — against your outline and the record, every flag with its source page.
